Abstract: 461,444. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 3, 1935, No. 27343. Convention date, Oct. 3, 1934. Drawings to Specification. [Class 38 (iii)] [Also in Group XXXV] Brake devices.-For obtaining low speed operation of a motor driving for example, a hoist, a mechanical brake is operated through hydraulic or pneumatic means including an impeller driven by an electric motor which is controlled to run at low speed for low-speed positions of the main motor controller and thereby to allow the brake to slip, and to run at full speed at other positions of the controller, thereby to release the brake completely. When the controller is moved from a high to a low speed position the motor driving the impeller may be placed under the control of a centrifugal switch or governor, and speed-controlled in accordance with the speed of the main motor so that a desired low speed is automatically maintained. A hand switch may be connected in parallel with the centrifugal switch for control by the operator. For maintaining a steady low speed the impeller motor may be connected to the rotor of the main motor if it is an alternating-current motor, or to a resistance in series with the motor if it is a direct-current motor. Alternatively, it may be connected to a machine driven by the main motor and operating as a frequency-changer. This machine may have low and high-pole numbers to give adjustment of the regulated speed. Specifications 363,137 and 385,042, [both in Group XXIX], are referred to.

Title: Improvements in or relating to apparatus for forming flexible metal tubing
IPC: B21C37/12
Filed: 1926-11-01
Abstract: 284,755. White, A. E., (Steeper & Hartley, Inc.). Nov. 1, 1926. Coiling; angular bending; reeling.- In the manufacture of flexible tubing from metal strip adapted for use as armouring for insulated electrical conductors, rubber hose &c., or as selfsustaining conduit for electrical conductors &c., the metal strip is positively fed at a predetermined rate from a strip supply on a rotatable support concentric about the axis of the tubing being formed and is deflected about the axis of the strip supply to cause the strip to be coiled into a flexible tubing without the use of. a mandrel or stationary strip coiling means. The apparatus comprises a pedestal 1 with semi-cylindrical seat 2 and cover 3 encicsing a space in which revolves a hollow sleeve 5 carrying a disc 11 with peripheral flange 8 for the driving belt 9. From the face of the disc project studs 10 with flanged rollers 12 engaging an internal rib 14 on the rim 13 of the stock reel, the latter being thereby rotatably supported concentric witb the axis of the sleeve 5. The metal strip 17 is retained on the reel between the flange 15 and pivoted fingers 16, and is led therefrom over slightly inclined guide rollers 18 on studs 19 projecting from the disc 11 to positively driven feed rollers 21 which are shaped to bend the strip to the required form previous to etching. The feed rollers 21 are mounted on shafts 27 carried by a bracket 22 pivoted to lugs on the disc 11, the bracket 27 being angularly adjustable by means of a pivoted screw 60 and nuts 61 to vary the pitch of the coil to be produced. The shafts 27 have intermeshing gears and one of them has a driving gear 28 meshing with a gear 30 keyed to a hollow sleeve 31 within the sleeve 5 driven bv change gearing 35, 36, 42 from a countershaft 40 driven by a pulley and belt 43, 44. The axle 37 of the change gear 36 is mounted in a slotted arm 38 on a quadrant 39 adjustable about the axle 40 of the gear 42 by the bolt and slot 45, 46. By changing the gear ratio the rate of feeding of the metal strip by the feed rolls 21 may be varied. After leaving the feed rolls 31 the strip is coiled into flexible tubing either for covering an insulated cable &c. or for forming a self-sustaining conduit T, as shown in Fig. 3, by means of coiling rolls 47 and coiling tools 48 adjustable radially on the disc 11, the axes of the rolls being inclined to the axis of the tubing being formed. In the operation of the machine the stock reel rotates about the axis of the disc 11 at a speed somewhat less than that of the disc itself and sets as a flywheel assisting in the smooth running of the disc. The machine may be stopped by a brake shoe 50 engaging the flange 8; the shoe is pivoted at 51 and operated by a foot lever 53 and rod 54. Another brake shoe 55 urged by a spring against the rim 13 of the stock reel prevents the latter overrunning as the disc comes to rest.

Abstract: 616,758 Looms. PEMBERTON & SONS, Ltd., and WAKEMAN, J. Sept. 12, 1946, No. 27378. [Class 142(iii)] A positive stop for a loom shuttle comprises a braking member A operated by a finger O<SP>1</SP> attached to the main crank arm N. The arrangement is such that when the shuttle B enters the box, the braking member is moved by the finger on the crank arm to a position in which it will always positively stop the shuttle when the shuttle has arrived at a predetermined position, independently of any action of the swell J. When the sley goes back, the finger on the crank arm moves away from the braking member and leaves the latter perfectly free so that it exerts no pressure on the shuttle when the pick takes place.
